COOKING STOVE OR RANGE.

SPECIFICATION forming part of Letters Patent No. 434,173, dated August 12, 1890.

Application filed March 17, 1890- Serial No. 344,130. (No model.)

To all whom it 1mg concern:

Be it known that we, GEORGE O. BERG- STROM, a citizen of the United States, and HANS N. HANSEN, a subject of the Emperor of Germany, both now residents of Neenah, in the county of Winnebago and State of Wisconsin, have invented a new and useful Improvement in Cooking Stoves or Ranges, of which the following is a specification.

Our invention relates to the application of a damper to a cooking stove or range at a point directly in the rear of the fire-pot and under that part of the stove-top which lies between the front and rear kettle-holes, whereby the direction of the principal portion of the heat-current which issues from said fire-pot can be controlled and directed at will under the rear holes of either the right or left hand side of said stove, as may be wanted upon any particular occasion, it being often dosirable to use the two front ones and the rear one, or rear ones, of but one side and to concentrate the heat toward that particular side, and thereby to lessen the consumption of fuel required to meet the demands of said occasion.

We attain said result by means of the arrangement of the damper, as illustrated in the accompanying drawings, in which Figure 1 is a plan of the top of an ordinary four-hole cooking-stove embodying our invention, the kettle-hole covers of its righthand side being left off and parts of the remaining ones and of the stove-top being broken away for the purpose of more plainly showing the fire-pot, its back wall, and the arrangement of our improvement in the rear of the fire-pot. Fig. 2 is a vertical section of the upper part of a cooking-stove upon the line a a of Fig. 1.

For the purpose of clearly identifyingthe different parts the top edges of the side walls of the stovein Fig. l and also of the damper of our improvement are shown in section.

Similar figures of reference indicate like parts in the several views.

1 represents a cooking-stove top, it being, as is usual, of several sections, and contains four kettle-holes; 2, the kettle-holes; 3, covers therefor; .4, smoke-flue outlet; 5, a damper of the usual construction in said outlet; 6, the top edges of the stove sides; 7, a damper representing our invention; 8, the firepot; 9, the fire-pot back.

In Fig. 1 the damper of our improvement is represented as being open upon the right and closed upon the left hand side of the stove, and directing the heat, as indicated by the arrow, under the rear holes of the righthand side.

The damper in Fig. 1 being swung toward the smoke-flue, as indicated in dotted lines 7 the heat from the fire-pot is permitted an unobstructed passage toward the smoke-fines at the rear.

We do not confine our invention to a particular form of damper or manner of operating it or a particular pointfor its location, as the. various patterns of cooking stoves and ranges having four or more kettle-holes will require modifications to meet their peculiarities of construction.

In Figs. 1 and2 the damperof our improvement is shown as being journaled in a step just in the rear of the fire-pot back upon the oven-top, the top end of its journal being journaled in the stove-top, which is provided with a countersink 1, into which said journal projects, and from a square 1 upon said projection can be operated by means of a socket-wrench applied thereto. It can be swung to either side or made inoperative-by swinging it toward the smoke-flue 4, as shown in Fig. 2.

What we claim, and desire to secure by Letters Patent, is-

In a cooking stove or range of the class described, the combination of the stove top having a countersink therein, the fire-pot, a damper arranged in a vertical position in the rear of said fire-pot between the front and rear kettle-holes of said stove or range, the journal of said damper projecting through the aforesaid countersink and the damper adapted to be turned by said projecting journal for permitting the free access of the heatcurrent from said fire-pot to the rear kettleholes of said stove or range or to deflect said currents to the kettle-holes of either the right or left hand side thereof, substantially as described.
